Pandemic Protocols, Native Nutrition: Grocery-Store Access from American Indian Reservations During COVID-19 with R. Akee and E. Simeonova, forthcoming in AEA Papers and Proceedings . 

Regular consumption of fresh and nutritious foods affects long-term health. However, residents of American Indian reservations travel substantially more than others for grocery shopping. These inequalities in access to amenities and infrastructure are mirrored in various health outcomes. Currently, Native Americans have 3.5 times the infection rate and 1.5 times the death rate from COVID-19 compared to non-Hispanic whites. We demonstrate that the social distancing policies, intended to slow the spread of the epidemic, may have additional, unanticipated effects on economic and health outcomes. We estimate the effect of Non-pharmaceutical Interventions (NPIs) on the type of grocery stores visited by individuals residing on and off of American Indian reservations during the COVID-19 pandemic. Using cell phone tracking data we examine how social distancing measures affected the average distance traveled to grocery stores. We find that there is a larger reduction in the overall distance traveled to grocery stores for on reservation households relative to off-reservation households. We also find evidence that the relative share of trips to convenience stores increases for reservation residents compared to those living off reservations. The shift toward convenience stores, which are less likely to sell fresh and nutritious foods, may exacerbate underlying morbidities and further increase health disparities in the long run.

Studying how state health services delivery policies can mitigate the effects of disasters on drug addiction treatment and overdose: Protocol for a mixed-methods study with Eisenberg M, Fingerhood M, McCourt A, McGinty EE, Rutkow L, Stuart E, Tormohlen K, and White SA, forthcoming in PLOS ONE.

 In response to the COVID-19 pandemic, U.S. states implemented multiple policies designed to mitigate disruptions to addiction treatment and overdose prevention services. This protocol paper proposes a mixed-methods design. Aims 1-2 use difference-in-differences analyses of large-scale observational databases to examine how state policies designed to mitigate the effects of the COVID-19 pandemic on health services delivery influenced addiction treatment delivery . Aim 3 uses a qualitative embedded multiple case study approach. ms 1-2 use difference-in-differences analyses of large-scale observational databases to examine how state policies designed to mitigate the effects of the COVID-19 pandemic on health services delivery influenced addiction treatment delivery .

A New Approach to Estimating Hedonic Equilibrium Models for Metropolitan Housing Markets. with D. Epple and H. Sieg, Journal of Political Economy, 128, No 3, 2020.

We provide a new estimator for a broad class of equilibrium models of metropolitan housing markets with housing differentiated by quality. Quality is a latent variable that captures all features of a dwelling and its environment. We estimate the model for Chicago and New York, obtaining hedonic housing price functions for each quality level for each metropolitan area, stocks of each quality, and compensating variations required for a household of a given income in Chicago to be equally well off in New York.

Market Access and the Concentration of Economic Activity in a System of Declining Cities. with P. Restrepo. REGION,  5(3), pp. 97-109. 

Market access has been widely used as a measure of agglomeration spillovers in models that seek to explain productivity, economic or population growth at the city level. Most results have shown that having higher market access is beneficial to these outcomes. These results, both theoretical and empirical, have been obtained in a context of population growth. This article examines the impact that market access has on a system of cities that has suffered a negative population shock. An extended version of the Brezis and Krugman (1997) model of life cycle of cities predicts that a system of cities experiencing population loss will see a relative reorganization of its population from small to larger cities, and that higher market potential will make this movement stronger. We test these predictions with a comprehensive sample of cities in Eastern Europe and Central Asia. We find that having higher market access - when operating in an environment of population decline - is detrimental to city population growth. This result is robust to different measures of market access that use population. Alternative measures that use economic size rather population are tested, and the result weaker. A possible explanation is that using NLs restricts the sample to only using larger cities.

Nature vs. Nurture vs. Nerd. with J. Imbrogno. Journal of Business, Industry, and Economics, 22, 41-65, 2017. 

We estimate an bayesian network model to predict the commission of a crime by juveniles in the US using an extensive set of information on the individuals. We use longitudinal survey data variables broadly categorized into three groups: Nature (related to family environment) Nurture (related to individuals’ relationship with his family that require active participation), and Nerd (variables describing schooling  performance). The Nerd attributes perform better at predicting crime than Nurture and Nature. Individually, none of these categories perform well in predicting the crime probabilities. A bundle of best predictors is determined, that correctly predict crime in 65.5% of the observations. This bundle has attributes from all categories, which suggests that it is necessary to address the issue of youth crime in all categories, even if educational policies receive special attention.​cities.

Cities in Eastern Europe and Central Asia: A Story of Urban Growth and Decline. with Grace Cineas, Paula Restrepo, and Sofia Zhukova. Washington, D.C.: World Bank Group. 2017. . 

This book provides a historical and contemporaneous analysis of the patterns of growth, and,  most importantly, decline, in the cities of the ECA region, including a discussion of the implication of urbanizing under planned economies and a discussion of recent demographic trends (migration and fertility). Particular importance is given to the region's urban systems and emerging trends in population and economic density using the a database collected specifically for this study. Despite an overall climate of decline, the book analyses underlying factors that could explain relative better performance. Finally, it covers the policy implications of the study’s empirical findings. The report is complemented by 17 country-level snapshots, which describe in detail country specific trends. The report is based on a unique city-level database collected specifically for it, which covers more than 5,000 cities in the region and provides harmonized data on economic activity, night lights and spatial measures, population, sprawl, urban multi-city agglomerations, and 1st order location fundamentals.  This database was published in the World Bank Data catalog.

Public Procurement: Autonomy vs Control. Chapter in the book A More Effective State: Capacities for designing, implementing and evaluating public policies. Bogotá: CAF. 2015. 

This book studies the role of the capacities of government agencies and institutions to design policies and put them into practice on the effectiveness of such policies. The chapter studies public procurement as an input in the production of governmental goods and services, and the implementation of public policies. It provides a comparative analysis of the systems in Latin American, and their connection to government effectiveness, as well as quantitative evidence of the relationship.

Ukraine Urbanization Review, (with Paula Restrepo, Benjamin Stewart, Katie McWilliams, and Sofia Zhukova).  Washington, D.C.: World Bank Group. 2015. 

This book links population dynamics with economic dynamics, and presents emerging spatial characteristics and trends. Ukraine has experienced a dramatic population decline over the past two decades, which impacts the urban system. The study uses historical data sets as well as historical maps. Part one outlines recent demographic changes and the impact of urban systems. Part two connects these dynamics to actions of local and regional governments. The final part analyses current urban and spatial planning practices and their shortcomings in view of changing demographics.
